Abstract

The invention discloses an oil product circulating purification device based on a polyamide melt-blown filter element. The oil product circulating purification device comprises an oil storage device, a hydraulic pump and a filter which are connected through pipelines; an oil product needing to be filtered is pumped into the filter from the oil storage device to be filtered by the hydraulic pump through the pipeline and then flows back into the oil storage device; the filter filters the oil product by adopting the polyamide melt-blown filter element, the filter element comprises an upper end cover, a lower end cover and a polyamide filter material, the polyamide filter material is obtained by treating a polyamide material through a melt-blowing technology, and superfine fibers blown out through the technology are mutually bonded and wound to form a hollow barrel-shaped structure; the filter material is of a loose structure, and filter holes of the different hole diameters are formed; the hole diameter size of the filter holes is distributed in the mode that the hole diameter size is sequentially and gradually decreased from the outer layer to the inner layer of the barrel-shaped structure. The oil product circulating purification device has the higher filter precision, assimilative capacity and oil-water separation capacity, has the advantages of resisting oil product corrosion, being high in reliability and the like and meets the filter requirement of the common oil products.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a filter device for oil purification. Background technique [0002] During the production, transportation and storage of engine fuel, a large number of impurities will be produced and mixed. Clean fuel oil will also produce pollutants such as metal oxides, precipitated colloids, and asphaltene after storage for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine's fuel injection system and combustion chamber, resulting in increased fuel consumption and a sharp increase in exhaust emissions after the engine has been used for a period of time. The current general solution is to install an oil filter on the engine to remove impurities, colloids, asphaltene and moisture in the fuel to make the fuel clean. Clean fuel can improve combustion efficiency, thereby saving fuel and reducing emissions; it can also reduce ab...
